Reasons

Maybe it was obvious, but I was angry for a very long time. Nothing appealed to me when I tried not to be angry. Instead I just felt anxious or sad. Angry was the easy solution.
It took a long time for me to get over it. I didn't want to talk, didn't want to know anything. Everything was a nuissance when it reminded me why I was angry. I just didn't want to think about it and distance was better.
And that's why I disappeared.
